Если ваш документ Word уже настроен с полями слияния, и вы запускаете макрос из книги, содержащей данные, которые вы хотите объединить в документ Word, попробуйте следующее:
Sub RunMerge()
Dim wd As Object
Dim wdocSource As Object
Dim strWorkbookName As String
On Error Resume Next
Set wd = GetObject(, "Word.Application")
If wd Is Nothing Then
Set wd = CreateObject("Word.Application")
End If
On Error GoTo 0
Set wdocSource = wd.Documents.Open("c:\test\WordMerge.docx")
strWorkbookName = ThisWorkbook.Path & "\" & ThisWorkbook.Name
wdocSource.MailMerge.MainDocumentType = wdFormLetters
wdocSource.MailMerge.OpenDataSource _
Name:=strWorkbookName, _
AddToRecentFiles:=False, _
Revert:=False, _
Format:=wdOpenFormatAuto, _
Connection:="Data Source=" & strWorkbookName & ";Mode=Read", _
SQLStatement:="SELECT * FROM `Sheet1$`"
With wdocSource.MailMerge
.Destination = wdSendToNewDocument
.SuppressBlankLines = True
With .DataSource
.FirstRecord = wdDefaultFirstRecord
.LastRecord = wdDefaultLastRecord
End With
.Execute Pause:=False
End With
wd.Visible = True
wdocSource.Close SaveChanges:=False
Set wdocSource = Nothing
Set wd = Nothing
End Sub
